Electro-mechanical scale



FIG. 1 is a top view of the electro-mechanical scale showing the new display design; and,

FIG. 2 is a right side view.

The left side view is a mirror image of the right side view.

The platform is shown in dashed lines. The dashed lines in the drawings indicate subject matter which form no part of the claimed design. The front, rear and bottom views have no particular aesthetic values and are therefore not considered part of the claimed design. 

The ornamental design for a display for an electro-mechanical scale, as shown and described.
